Abstract (en)
[origin: EP0377089A1] The cooling of cracked gas is served by a heat exchanger having a tube bundle held between two tube plates (2), and two terminal chambers (4) which adjoin the tube plates (2) and narrow to form a socket (5). Arranged in the terminal chamber (4) on the inlet side are inserts which consist of rods that are bent to form round or polygonal, concentrically arranged rings (7). The rings (7) are arranged at a distance from the tube plate (2) in an extension of the socket (5) on the inlet side, and preferably along the surface of a cone pointing with the apex towards the gas inlet, on a surface which essentially corresponds to the cross-sectional surface of this socket (5). <IMAGE>
